IMPROVEMENT IN WARP-BEAM APRONS FOR LOOMS.

Specification forming part of Letters Patent No. 171,519, dated December 28, 1875; application filed October 521, i 75.

To all whom it may concern:

Be it known that I, LEONARD J. LABOUNTY, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Looms for Weaving Textile Fabrics, of which the following is a specification:

My invention relates and is applicable to that part of a loom known as the beam, upon which is 'wound the warp used in weaving textile fabrics; and consists of an improved device connected to said beam by means of an apron or its equivalent, by which a saving is made of the warp upon the beam, and a more even tension is given to the warp in weaving the last end of the web.

The accompanying drawing illustrates my invention.

A is a beam, upon which is wound the warp preparatory for weaving. B is the warp. O O O O are leather or other suitable bands, fastened at one end to the beam A, and at the other end to the strap D, forming together what I term an apron. E E E E are hooks fastened to the straps O G O O, and formed to receive the clamp-rod F, and retain the same in its place. F is a rod,bent at an equal distance from each end, and of sufficient length to extend across the entire width of the warp, besides allowing a suflicient length outside of the warp necessary to be held by the outside hook.

The operation of my improved device is as follows: NVh'en the warp is in a condition to be wound upon the beam one arm of the bent clamp-rod F is placed upon the upper surface, and the other arm beneath the upper surface,

of the warp. The rod is then turned over, so

sume the entire portion of the warp to within a short distance of the clamp-rod,b ecause the being fastened to the beam, and the other intended to receive the hooks E E E E.

I do not claim an apron used either separately or simply in combination with the beam; but

What I do claim is- The clamp-rod F, in combination with an apron or bands, 0 O O 0, attached to the warp-beam of a loom for weaving textile fabrics, substantially as and for the purpose herein specified.
